Protected crop production facilities such as greenhouse and plant factory have drawn interest and the area is increasing in Korea as well as in other countries in the world. Remote control systems using either mobile devices (e.g., cell phone) or internet-accessible computers have been developed. Application of smart-phone has been tried to support communication with both text message and internet access recently, but performance tests at various conditions have been limited. Objectives of the paper were to construct a greenhouse simulator that the environments could be controlled electronically and automatically, and to evaluate remote control of the environments using mobile devices in various conditions. A small-sized greenhouse with dimensions of 2.6´3.8´2.2 m (W´L´H) was constructed as a simulator. Control factors were window motor, ventilation fan, light, heater/cooler and solenoid valve for irrigation, and sensing variables were air temperature and humidity, luminous intensity, and soil water content. Performance of the wireless control network was evaluated as control response time by number of control node, power consumption of the wireless control network.
